Coronary Intervention & Surgery

 

A cross-sectional study of nearly 1,300 patients revealed Chinese physicians systematically overestimate the severity of coronary stenosis, perhaps even more so than in the United States, likely leading to many patients being inappropriately treated with percutaneous coronary intervention (PCI).

The risk of another heart attack following percutaneous coronary intervention (PCI) was twice as likely to originate from a previously untreated lesion versus the stented lesion, according to a study of a large Swedish cohort published in the Journal of the American Heart Association.

Patients are significantly more likely to die within one year of coronary artery bypass graft (CABG) surgery or PCI in New York state than in England where the procedures are roughly four times cheaper, according to a study in Open Heart.

Temporarily cooling part of the heart during myocardial infarction (MI) and again immediately after angioplasty may reduce damage to the heart, said a cardiologist who participated in the first in-human study of the technique.

Charles E. Chambers, MD, spoke with Cardiovascular Business about the risks of radiation exposure to interventional cardiologists and potential solutions.

Medtronic’s TAVR platform approved for expanded use by FDA

The U.S. Food and Drug Administration (FDA) has approved the use of a self-expanding transcatheter aortic valve replacement (TAVR) platform on patients with symptomatic severe aortic stenosis who are at an intermediate risk for open-heart surgery.

Want to predict mortality in elderly TAVR, SAVR patients? Use this four-item scale

It’s logical that frailty factors into recovery from major heart surgery. But what, exactly, is the best method for judging a patient’s frailty before transcatheter or surgical aortic valve replacement (TAVR/SAVR)? A study published online July 7 in the Journal of the American College of Cardiology explored this question by examining seven frailty scales in predicting poor outcomes.

3D-printed models could predict leakage location, severity in TAVR

New manufacturing methods can further personalize medicine—and now 3D printing may offer cardiologists a method of testing transcatheter aortic valve replacements (TAVR) for leakage before implantation.

New research on a heart pump designed to treat cardiogenic shock patients receiving a percutaneous coronary intervention (PCI) suggests that early placement of the device can boost survival rates.
